带有 ssh 的 svn：身份验证失败

我正在尝试更新远程 Subversion 存储库，但失败了。尝试调试它，这是消息：

我已将 ~/.ssh 重命名为 ~/.ssh_backup 并重复该过程，但问题仍未解决。我还尝试通过以下方式强制 ssh 要求键盘身份验证：

export SVN_SSH="ssh -v -o PubkeyAuthentication=no"

但它仍然不要求键盘认证。

我的问题是（互补）：

  1. 我该如何帮助解决身份验证问题？
  2. 我可以强制进行键盘验证吗？这是一个临时的解决方案？

答案1

您不能强制客户端使用服务器不提供。如果是，那么客户端将在公钥失败后尝试自动使用它。

换句话说，服务器管理员已禁用除之外的所有其他身份验证机制publickey，因此您必须与他们讨论为什么您的密钥（id_rsa 文件）不被允许访问。

服务器端的身份验证设置在 中/etc/ssh/sshd_config。
